What shift solenoid E does depends on the transmission. On Ford's 6R80 and 6F35/6F55 it is an on/off valve that moves a multiplex valve, so solenoid D feeds either the low/reverse brake or the 4-5-6 clutch; on the 6R140 and 5R110W it is a proportional clutch valve with separate short codes (P0985/P0986). On Saab's Aisin 5-speed E is valve S1. P0774 is an intermittent electrical fault in the circuit of solenoid E. No manufacturer document available to us uses it: Ford's solenoid E table has no intermittent code, and GM's Allison tables catch intermittent cases through the pressure switch check. A loose contact or chafed wire is the likely cause.

Likely causes

Loose contact or corroded connector
Chafed harness
Coil with heat-dependent winding fault

Symptoms

  • Limp mode or harsh shifts at times
  • Warning lamp comes and goes
